At trillions of degrees of heat:

"In the first millionths of a second after the Big Bang, the universe was a roiling, trillion-degree plasma of quarks and gluons—elementary particles that briefly glommed together in countless combinations before cooling and settling into more stable configurations to make the neutrons and protons of ordinary matter.

"In the chaos before cooling, a fraction of these quarks and gluons collided randomly to form short-lived "X" particles, so named for their mysterious, unknown structures. Today, X particles are extremely rare, though physicists have theorized that they may be created in particle accelerators through quark coalescence, where high-energy collisions can generate similar flashes of quark-gluon plasma.

"Now physicists at MIT's Laboratory for Nuclear Science and elsewhere have found evidence of X particles in the quark-gluon plasma produced in the Large Hadron Collider (LHC) at CERN, the European Organization for Nuclear Research, based near Geneva, Switzerland.

"The team used machine-learning techniques to sift through more than 13 billion heavy ion collisions, each of which produced tens of thousands of charged particles. Amid this ultradense, high-energy particle soup, the researchers were able to tease out about 100 X particles, of a type known as X (3872), named for the particle's estimated mass."

Comment: I am not a physicist studying cosmology and the circumstances of the Big Bang. That quark-gluon plasma made up all of the matter of the eventual universe and contained enormous heat. From nothing? Not likely. The physicists act as if they really believe the hot Big Bang is real if they run experiments mimicking it. Guth et. al. proved to all at Hawkins' 60th birthday party celebration the BB had no past, so it had a mysterious start. God or ?.
